Multi-channel gas detection control unit GMA22-M

LCD display

Gases are also used (or may be found) in smaller facilities such as combined heat and power plants or cold stores. A reliable gas detection system therefore makes a significant contribution to the safety of people, your equipment and the environment. We developed the GMA22-M specifically for gas measurement in these applications. Up to four transmitters and relay modules can be connected to the controller. A display indicating the measured values, integrated visual and audible alarms, and four internal relays for additional safety measures complete the GMA22-M's extensive features. Gases need to be monitored in many processes - regardless of the size of the plant. Even in smaller applications, a gas warning system is indispensable. The GMA22-M is the ideal controller for this purpose, if your application uses up to four transmitters you need to monitor toxic and combustible gases or oxygen a central display of measured values is required outside hazardous areas internal or external relays are required for safety measures you want acoustic and visual alarms to be initiated if gas dangers are present Wide range of connection options Using its RS-485 interface, the GMA22-M can be connected to up to four transmitters. In addition to the measured values, the controller also receives digital information such as status messages and service notifications. Alternatively, transmitters can also be connected through an analog 4-20 mA or 0.2-1 mA input. If you are using any of GfG's ACDC capable transmitters, the analog lines can also transfer digital information on the analog lines (only via 4-20 mA).
